Wait. Benoit, you mean restart the laptop or stop/start HBase? I agree that
contents of /tmp are not stable across system reboot, across stop/start of
HBase process there should be no problems. Should.

For what it's worth, on the Mac and local mode testing, I usually use
$HBASE_HOME/data. This is usually not on /tmp.
